The purpose of this study is to replicate the original experiment conducted by Eskine, K.J., Kacinik, N. A., and Prinz, J. J., (2011) which tested the hypothesis that moral judgments are influenced by taste-induced emotional states. This close replication takes place at Brunel University London in the context of the level 2 BSc Psychology module PY2605 (Quantitative Research Methods). ### Original abstract of Eskine et al. (2011) Can sweet-tasting substances trigger kind, favorable judgments about other people? What about substances that are disgusting and bitter? Various studies have linked physical disgust to moral disgust, but despite the rich and sometimes striking findings these studies have yielded, no research has explored morality in conjunction with taste, which can vary greatly and may differentially affect cognition. The research reported here tested the effects of taste perception on moral judgments. After consuming a sweet beverage, a bitter beverage, or water, participants rated a variety of moral transgressions. Results showed that taste perception significantly affected moral judgments, such that physical disgust (induced via a bitter taste) elicited feelings of moral disgust. Further, this effect was more pronounced in participants with politically conservative views than in participants with politically liberal views. Taken together, these differential findings suggest that embodied gustatory experiences may affect moral processing more than previously thought. ### Study Materials In the Files -> Materials section, we have the following documents: * [The original Vignettes](https://osf.io/mhqes/) * [A version of the distractor task created by a CREP participant](https://osf.io/8q467/) * [Our version of the manipulation check](https://osf.io/bwunt/) Note: In our version of the manipulation check, we changed the 'political orientation' question to bring this question in line with the UK political system. The rest of this document is virtually unchanged from the original. Additionally, the script of the Qualtrics survey that we used to present the tasks can be found [here](https://osf.io/vfzjp/), and the accompanying session script (to promote consistency and data quality with student researchers) can be found [here](https://osf.io/fj3qm/) (both based on materials developed by [Urry and colleagues](https://osf.io/ddmkm/)). ### Study Ethics In the Files -> Ethics section, we have the following documents: * [Subject information sheet](https://osf.io/j4afg/) * Ingredient lists for the [bitter](https://osf.io/mtks8/), [sweet](https://osf.io/9nqj5/), and [neutral](https://osf.io/7rc5y/) beverages * [Consent form](https://osf.io/k67cm/) * [Debrief form](https://osf.io/t2p9y/) Note 1: We used the non-alcoholic Swedish Bitter from http://www.granaryherbs.co.uk/. Note 2: As Minute Maid Berry Punch is not available in the UK, we used [Morrisons 100% Fruit - Red Grape and Berries Juice][1]. This contains 12.1g of sugar per 100ml, which is similar to the Minute Maid Berry Punch. Its flavour is mainly from grape juice (70%) and apple juice (10%) with a little strawberry and raspberry puree added to modify the colour and change the taste so it's not exactly the same as every other juice and smoothie. The Minute Maid Berry Punch is mainly flavoured with grape juice, with a tiny amount of added strawberry and peach. ### Procedure video A video of our procedure can be found [here](https://osf.io/xfv59/), and the youtube link to the same video can be found [here](https://youtu.be/uOVh3FqcSvI) ### Data & Results The data & results wiki can be found [here](https://osf.io/d2c4z/), containing the links to the files. ### Recommendation from the original author "I recommend your students practice "selling" the cover story as described in the methods." ### Notes from CREP Team To obtain a CREP replication reward the minimum N for this project is 57. **Cover Story**. Some questions arose during the course of the replication in regards to the cover story. It is described in the paper and in the informed consent form. Because we could not get in touch with the original author, we have created a new cover story based on the consent form and the method of the paper. Please read the following to participants: "In this study you will be asked to read several vignettes and make judgments about the characters in them. Your job will be to judge the actions of the characters. During this task, you will be asked to drink a beverage. The purpose of this study is to determine whether motor movements involved with drinking influence your judgments while reading about others. In order to successfully attain this, please drink each dose in a single swift motion, as if you were drinking a shot." **Swedish Bitter** The brand of the Swedish Bitter was not identified, and we could not get in touch with the original author. Given that Swedish Bitters are likely comparable, we suggest any brand to be acceptable for this study. [Other FAQs here][2].
